Abstract: Im folgenden soll über eine Reihe von Arbeiten berichtet werden, die im Physikalischen Institut der Rheinisch-Westfälischen Technischen Hochschule Aachen und im Institut für Plasmaphysik der Kernforschungsanlage Jülich durchgeführt worden sind. / In this paper recent work at the Physics Institute of the University of Technology Aachen and the Institute of Plasmaphysics of the Nuclear Research Center Jülich is reported. In the first part the hydromagnetic theory of bearings is given. At first the hydromagnetic case of a flow between two plane plates slightly inclined towards each other is calculated. The results are applied to the case of theflow of an electrically conducting fluid in a cylindrical bearing. In analogy to the treatment in the hydrodynamic theory of bearings similarity laws have been derived. In the hydromagnetic case these laws could be calculated explicitly only in the limiting case of high magnetic fields. The effective viscosity is found to be equal to the product of the Hartmann number and the mechanical viscosity. In the second part of the paper magnetically driven shocks of high values of the Mach-number are discussed. The planarity of the luminous front has been studied by streak-camera photographs. The velocity of the luminous front as a function of the distance from the shock-generating coil and of the initial pressure have been measured. Precursor signals and the electron temperature immediately behind theluminous front have been measured with the help of time resolved spectroscopy. Finally some of the experiments in high-temperature-plasma-physics have been discussed and the status of these experiments with regard to an experiment with positive energy balence has been evaluated. As a result, one can say, that with the help of theta-pinch a plasma with densities of some 10$^{17}$ 1/cm$^{3}$ and an temperature of about 1 ke V can be generated and kept stabil for microseconds, so that the essential parameters can be measured with reasonably small errors.
